	1	Femtosecond Spectroscopy Studies on YBa_(2)Cu_(3)O_(7-x) and PrBa_(2)Cu_(3)O_(7-x) a Epitaxial Thin Films显示文摘We report the results of femtosecond spectroscopy studies on YBa_(2)Cu_(3)O_(7-x )and PrBa_(2)Cu_(3)O_(7-x )(x=0.1)epitaxial thin films at room temperature.The transient reSectivity signals ΔR(t)in the samples are consistent with a band filliitg model.The relaxation times of ΔR(t)in YBa_(2)Cu_(3)O_(7-x ) increase from less th&n 100 fs to more than Ips with increasing x and with substitution of Pr for Y.These results reveal that in high Tc superconductors decrease of carrier concentration slows down the carrier-phonon coupling.

	2	Thermal Fatigue Behavior of SiC/MBAS Glass Coated Carbon/Carbon Composites显示文摘The thermal fatigue behavior of C/C composites coated with the SiC/MBAS glass (MoSi2 particle-containing boron aluminosilicate glass) coating, prepared by the two-step process of the pack cementation and procoating-sintering, was investigated in present paper. The experimental results indicated that the SiC/MBAS glass coating had an excellent thermal shock resistance in air at temperature up to 1873 K. During quick thermal cycle between 1873K and room temperature in air, the decrease of mass and mechanical property of the coated C/C composites was all slight. After thermal cycle for 50 times, the mass loss of the SiC/MBAS glass coated sample was only 0.22%; additionally, the remaining ratio of strength and modulus was no less than 95.2% and 99.4%, respectively. The decrease of the mechanical property during the thermal cycle was primarily due to the damnification of the fiber/matrix interfaces and the oxidation of the coated samples with oxygen.
